The Basics

What Is an Online Timed Auction — and Why Run One?

An online timed auction is a bidding sale that runs entirely over the internet, with a fixed closing time set in advance. Unlike a live auction with a human auctioneer, a timed auction is fully automated: you set the start time, end time, and opening bid for each lot — then the software handles every bid, every increment, every outbid notification, and every invoice.

Bidders visit your website, register, browse your lots, and place bids at any hour of the day or night. When the countdown expires, the highest bidder wins automatically. No gavel. No venue hire. No staff on auction day.

This format is used for everything from antiques and collectibles to industrial equipment, luxury goods, property, and surplus stock. If you have items with buyers, a timed auction is the most efficient and scalable way to sell them online under your own brand — not through a marketplace that takes a cut and owns your buyer relationships.

The key advantage over a general marketplace or competitor SaaS tools: this is timed auction software you own outright — the software, the data, and the domain are all yours. Your buyers are your buyers.

Before You Start

What You Actually Need to Get Started

No surprises. This is the honest checklist — every item you need before your first auction can go live.

Items to sell

Anything with a market — antiques, industrial equipment, surplus stock, collectibles, property, vehicles. The software handles any category. You supply the inventory.

A domain name

Your auction site lives at your own URL — yourauctions.com, yourbrand.co.uk, whatever fits your business. From £8/year with any registrar.

Web hosting or a managed plan

If you choose the software license, you need a PHP-capable hosting account — shared hosting from ~£5/month works. Or choose our managed VPS plan and skip this entirely: we handle the server.

A payment gateway

PHP Pro Bid integrates with Stripe, PayPal, and others out of the box. Buyers pay through your gateway — money goes directly to your account. We never touch your revenue.

Buyers

Your first bidders come through marketing — social media, email, SEO, word of mouth, or existing customer lists. PHP Pro Bid gives you buyer registration, verification, and a built-in messaging system to engage them.

Optional

Technical knowledge

Our managed plan needs zero technical skill. For the self-hosted license, basic FTP and cPanel access is enough. One-click install handles the rest. Full documentation included.

Step-by-Step Guide

How to Set Up and Run Your First Timed Auction

From a blank slate to active bids. Each step links to the relevant documentation so you can go as deep as you need.

1

Install and configure your platform

After ordering, install PHP Pro Bid on your hosting account using the one-click installer. Set your site name, timezone, currency, and language. This takes under 30 minutes. Choose the Managed plan and we handle this for you — your platform arrives pre-configured and ready to customize.

View installation docs →
2

Configure your auction settings

Set your bid increment rules — flat amounts or an increments table that scales with the lot price. Configure proxy bidding so the software automatically bids on a buyer's behalf up to their maximum. Enable bid sniping protection: any bid placed in the final moments automatically extends the auction by a time period you define, ensuring a fair close.

3

Set up buyer registration and verification

Choose your registration flow: open registration, email activation, or admin approval. Enable buyer verification — an identity confirmation step that builds trust between you and your bidders. All registration data is stored on your server. Configure the password rules, welcome emails, and KYC requirements that fit your market.

4

List your lots

Create each auction listing with a title, description, images, opening bid, and reserve price. Set a custom start and end time for each lot, or use a fixed duration. Upload up to multiple images per lot. Save drafts and publish when ready. For large sales, use bulk listing upload to create dozens or hundreds of lots from a spreadsheet in minutes rather than hours.

5

Set your fee structure

Charge listing fees, sale transaction fees, or both — paid by sellers, buyers, or split. Fees can be percentage-based, flat, or tiered by price range. Use the built-in fees calculator so buyers can see the total cost before they bid. Configure buyer's premium if your market expects it. Every fee is set by you and goes directly to you.

Fees configuration docs →
6

Connect your payment gateway

PHP Pro Bid integrates with Stripe and PayPal out of the box. Connect your gateway from the admin panel — no code required. When a buyer wins and pays, funds land in your account. The Stripe add-on supports Payment Intents API with automatic card charging, so buyers check out in one step.

7

Go live and monitor in real time

Publish your lots and open registration. Buyers start bidding. Your dashboard shows every active lot, bid count, current price, and time remaining in real time. Outbid notifications go out automatically to losing bidders — bringing them back to rebid without any manual effort. When the timer reaches zero, winners are determined and invoices generated automatically.

Bidding documentation →
8

Post-sale: invoicing, payment, and dispatch

When bidding closes, the platform auto-generates invoices for every winning bidder. Buyers receive an email with a link to pay and arrange shipping. Combine multiple lots into one invoice for buyers who won more than one item — a feature that reduces friction and increases collection rates. Unsold lots can be relisted with one click.

FAQ

Questions about online timed auctions

Everything first-time platform owners ask before going live. More in the full documentation.

Ask a question →
What is an online timed auction?
An online timed auction is a bidding sale that runs over the internet with a fixed closing time. Buyers place bids at any time during the auction period. When the countdown reaches zero, the highest bidder wins automatically. No auctioneer is required. The software handles all bid increments, outbid notifications, and invoicing.
Can I run my own online auction without technical experience?
Yes. On the managed plan there's nothing to install — your platform arrives set up and ready, and you simply add your lots. If you'd rather self-host, a one-click installer and step-by-step documentation guide you through it. You don't need to be a developer to run your own auctions.
How much does it cost to run an online auction?
Two simple options: a one-time £399 license you own outright, or the Cloud plan from £63/month. Either way, there are no per-sale commissions and no transaction fees taken from winning bids — you keep what you earn. You'll also need a domain (from about £8/year), and basic hosting if you choose the license.
How is PHP Pro Bid different from using a general marketplace?
With a marketplace, buyers belong to the marketplace, not you. PHP Pro Bid runs on your own domain. There are no transaction fees paid to us. You set your own rules, fees, and brand. When buyers visit your site, they see only your auction house, not competitor listings.
What happens if a winning bidder doesn't pay?
PHP Pro Bid includes buyer verification, account reputation, and a direct payment system. If a buyer does not pay, you can flag their account, restrict their access, and relist the lot. The platform gives you the administrative controls to manage non-paying bidders from the admin panel.
Can I run timed auctions and a shopping cart on the same platform?
Yes. PHP Pro Bid includes a full shopping cart module alongside auctions. You can sell items at fixed prices and via timed bidding on the same website, under the same buyer accounts. This is a significant advantage over auction-only platforms, which require separate systems for fixed-price sales.
What is bid sniping and how does the software prevent it?
Bid sniping is when a buyer places a winning bid in the final seconds of an auction, giving other bidders no time to respond. PHP Pro Bid prevents this with automatic bid extension: when a bid is placed within a configurable final period (e.g. the last 5 minutes), the auction closing time is automatically extended. This ensures a fair competition and typically results in higher final prices.
How many lots can I list in a single timed auction?
There is no hard limit on the number of lots. PHP Pro Bid supports large catalogs across a single auction or multiple simultaneous auctions. Use the bulk listing upload feature to import hundreds of lots from a spreadsheet. Stagger closing times to spread buyer attention and maximize final bid activity on each lot.
Can I run my auction platform in multiple languages?
Yes. PHP Pro Bid includes a full multilanguage system with a translations pack for common languages, so you can run your auction site in multiple languages for international buyers. Your auction's currency is set by you from the admin panel — you choose the currency your platform runs in, rather than it changing per buyer. This multilanguage support gives PHP Pro Bid a meaningful advantage over platforms that are English-only by default.
